I began in Red Hat 9.
I see root=/dev/hda2 always works for me in
/etc/grub.conf.
I see the root=LABEL=/ supplied by the `make install`
here panics any kernel I boot after building after
fetching source from kernel.org rather than from
redhat.com.
Anyone know why? Or how I can find out?
Since root=/dev/hda2 always works for me, I don't Need
to know why root=LABEL=/ only sometimes chokes, but
I'm curious, all the same.

Specifically, when I reboot what I built & installed,
I see:
VFS: Cannot open root device "LABEL=/" or 00:00
Please append a correct "root=" boot option
Kernel panic: VFS: Unable to mount root fs on 00:00
Except with later kernels I see:
VFS: Cannot open root device "LABEL=/" or
unknown-block(0,0)
Please append a correct "root=" boot option
Kernel panic: VFS: Unable to mount root fs on
unknown-block(0,0)
Transcribing the earlier panic into Google yielded the
suggestion that I edit what `make modules_install &&
make install` originally wrote into /etc/grub.conf as:
title Red Hat Linux (2.5.72-pel)
root (hd0,0)
kernel /vmlinuz-2.5.72 ro root=LABEL=/
initrd /initrd-2.5.72-pel.img
Specifically I tried root=/dev/hda2 ... for me that
works great in 2.4.20, 2.4.21, 2.5.69, and 2.5.72.

On my own, I figure I will pursue:
http://www.redhat.com/docs/manuals/linux/RHL-9-Manual/custom-guide/s1-custom-kernel-additional-resources.html
http://www.redhat.com/mirrors/LDP/HOWTO/Kernel-HOWTO/
http://www.redhat.com/mirrors/LDP/HOWTO/Kernel-HOWTO/grubconf.html
Also Google of the newer panic.
